[gnome-shell] Use meta_window_is_skip_taskbar() directly

[Florian Müllner <fmuellner src gnome org>]

commit b4680a5c253ac1d1b3d847a5f94150c6e8122fba
Author: Florian Müllner <fmuellner gnome org>
Date:   Thu Jan 30 18:04:18 2014 +0100

    Use meta_window_is_skip_taskbar() directly
    
    Rather than going through ShellWindowTracker, we can just clean up
    the code to use the underlying MetaWindow property directly.
